Question

我是Cosmos DB的新手。我试图执行一个存储过程，它只是根据id获取所有文档并更新每个文档的一个属性。执行时无法执行。

这个存储过程出了什么问题？

string database = ConfigurationManager.AppSettings["database"];
string collection = ConfigurationManager.AppSettings["collection"];
client = new DocumentClient(new Uri(EndpointUrl), PrimaryKey);

DocumentCollection obj = await DocumentClientHelper.GetOrCreateCollectionAsync(client, database, collection);
string scriptFileName = @"E:\Satyaray\NoSql\NosqlDemoConsole\NosqlDemoConsole\Updatevalue.js";
string scriptId = Path.GetFileNameWithoutExtension(scriptFileName);

var sproc = new StoredProcedure {
   Id = scriptId,
   Body = File.ReadAllText(scriptFileName)
};

await DocumentClientHelper.TryDeleteStoredProcedure(client, obj, sproc.Id);

sproc = await client.CreateStoredProcedureAsync(obj.SelfLink, sproc);

var response = await client.ExecuteStoredProcedureAsync < string > (sproc.SelfLink, new RequestOptions {
PartitionKey = new PartitionKey("XMS-0001")
}, "XMS-001-FE24C");

存储过程

function simple(id) {
    var collection = getContext().getCollection();
    var collectionLink = collection.getSelfLink();

    getAndUpdatedata();

    function getAndUpdatedata() {

        var isAccepted = collection.queryDocuments(
        collection.getSelfLink(),
        'SELECT * FROM root r where r.id=' + id,
        function (err, feed, options) {
            if (err) throw err;

            for (var i = 0; i < feed.length; i++) {
                var metaDoc = feed[i];

                metaDoc.readingTime = new Date();
                var isAccepted = collection.replaceDocument(metaDoc._self, metaDoc, function (err) {
                    if (err) throw err;

                });
                if (!isAccepted) throw new Error("The call replaceDocument(metaDoc) returned false.");
            }


        });

        if (!isAccepted) throw new Error("The call queryDocuments for metaDoc returned false.");
    }
}

我使用console.log打印你的sql，我发现它看起来像：

SELECT * FROM root r where r.id= XMS-001-FE24C

实际上，它应该是：

SELECT * FROM root r where r.id= 'XMS-001-FE24C'

因此，请稍微修改存储过程中的SQL，它可以正常工作：

var isAccepted = collection.queryDocuments(
    collection.getSelfLink(),
    "SELECT * FROM r where r.id = '" + id + "'",
    ......

BTW，id是用户定义的资源的唯一名称，提到here。所以我认为你的sql的结果应该只包含一个数据，不需要循环feed数组。

希望它对你有所帮助。
